MACHINE FOR MARKING ROUND OBJECTS.

SPECIFICATION forming part of Letters Patent No. 431,477, dated July 1, 1890. Application filed February 28, 1890. Serial No. 342,141. (No model.)

To all whom it may concern.-

Be it known that I, HARVEY S. PAGE, of the city of St. Louis, in the State of Missourhhave invented a certain new and useful Improvementin Machines for Marking Round Objects, of which the following is afull, clear, and eX- act description, reference being had to the accompanying drawings, forming part of this specification.

This is a machine for marking broom-handles and other objects circular in cross-section, whether cylindrical or tapering.

The features of novelty are set forth in the claims.

Figurel. is an end elevation of the machine. Fig. II is a detail front elevation. Figs. III and IV are vertical sections of the table at III IV, showing the carriage in its retracted and advanced positions, respectively. Fig. V is a top view with parts in normal position.

1 is a stand. which may be of any suitable construction.

2 is the top or table.

3 is a case, in which are fitted one or more movable printing block or blocks 4. A nu m ber of these blocks are generally used, and they are made interchangeable, so that the design may be altered at will. Each block 4 is sustained by springs 5,whose upper ends rest in recesses of the block, or are otherwisesecured to it. The blocks will thus accommodate them selves to any irregularity or curvature of the object being marked by descent of the block in whole or part. The upward movement of the block is limited by projectors 6 upon the ends of the block, which engage beneath the inturned flanges 7 at the upper edges of the sides of the case 3. The case 3 may be attached to the frame 1 or table 2 in any suitable manner, and may have a removable bot tom 8, as shown, to allow the insertion of the blocks from the under side of the case. One end 9 may be removable, as indicated in Fig. V, for the insertion of the blocks 4: at that end of the case, 10 being screws by which the end is held in place. The blocks have flexible characters 11, making the form, and preferably of soft rubber, although other flexible material-for instance )rinters ink roller compositionmaybe used. The faces of the characters 11 are normallyin the same plane,

being sustained in this position by the springs 5.

At 12 are seen two movable side guides, against which the object 13 is placed at the beginning of the marking process, and 14 is a movable end guide, against which the end of the object is placed at this time. The guides are held in place by screws 15, which pass through transverse and longitudinal slots 16 in the table, so that the guides may be adjusted as required.

The surface of the printing-blocks being exposed and unobstructed, the object, as also the inking-roller, may of course be rolled over the yielding blocks 4 by hand; but I prefer to do this and at the same time ink or paint the form by devices which will be now described.

, 17 is a carriage working between guides 18 of the table, and having a lug -19 connected to a lever 20 by a pin 21. The pin is fast in the lug and works in a longitudinal slot 22 of the lever, allowing the carriage to move in a straight line,wl1ile the end of the lever moves in the arc of a circle. The lever is fulcru med to the frame 1 at 23. The lower end of the lever is connected by a pin 21 to a sliding treadle 25, which is slotted at 26 and works on a guide-pin 27, that passes through the slot. It will be seen that when the treadle is pushed backward by the foot that the carriage is moved forward.

28 are standards of the carriage, in which the gndgeons 29 of the paint or inkroller 30 have bearing. The paint or ink is applied to the rollerby another roller, or in any other suitable way. The position of the roller 30 is such that when the carriage moves forward the roller rolls over the form and paints or inks it. i

31 are fingers, of which one is connected to each of the standards 28 by a pivot 32. The fingers are drawn down by springs 33 against a stop-stud 34. The position of the fingers is such that they pass over the object 13 when the carriage moves forward, pressing against its upper side, and causing it to roll over the form.

35 is a spring whose oflice is to draw the carriage 17 back into its normal position, as seen in Figs. I, III, and V.

The operation is as follows: The guides 12 are so arranged that when the object 13 has made a single rotation it may reach the forward edge 36 of the form, so that the design may encircle the object without lapping over at the point of meeting. The end guide 1a is arranged to bring the proper part of the object to the form. The object is now'laid against the guides and on the form and the treadle pushed forward, the fingers 29 roll the object over the form, and the roller 30 paints or inks the form for the next operation. On release of the treadle the spring 35 carries the carriage 17 back into normal position, and the operation is repeated.

- I claim as new and of my invention- 1. The combination, with a movable printin g-block 4, of a supporting-spring 5, substantially as set forth. I

2. The combination of the block 4, having an exposed unobstructed printing-surface, and a spring supporting said block, substantially as set forth.

3. The combination of a fixed case and a printing-block having movement iii the case, and a supporting-spring beneath the marking-block, substantially as and for the purpose set forth.

4. The combination, in a device for marking round objects, of a fixed case and provided with an exposed unobstructed printin gsurface, movable blocks having" bearing in said case, and springs beneath the blocks, substantially as and for the purpose set forth.

5. The combination, in a device for marking round objects, of two or more interchange able printingblocks, springs beneath the blocks, anddevices, substantially as set forth,

blocks having an elastic face and movable in r a case or frame, and independent springs supporting the blocks, substantially as and for the purpose set forth.

7. The combination, in a machine for marking round objects, of a marking-form and a carriage carrying fingers adapted to roll the object on over the form by the movement of the carriage, substantially as set forth.

8. The combination,in a machine for marking round objects, of a form adapted for the objects to be rolled over it, and a carriage carrying fingers adapted to roll the object over the form, and a roller adapted to paint or ink the form, all substantially as set forth.

9. The combination, in a machine for marking round objects, of a marking-form,adjustable guides 12, and the movable fingers for rolling the object over the form and for painting or inking the form, substantially as and for the purpose set forth.

10. The combination, in a machine for marking round objects,0f'a marl;;ing-form,adjustable guides, carriage having fingers adapted to roll the object over the form, roller adapted to paint or ink the form, the carriage-actuating treadle, and levers with return-sprin g, all substantially as set forth.
